test/7 gnome: Fix on ICC and suppress a warning

Ignore warning 2282 about GCC pragmas since they are emitted in system
headers and are extremely spammy. They are emitted because ICC pretends
to be GCC via C macros but doesn't implement some pragmas.

https://bugzilla.gnome.org/show_bug.cgi?id=776562

Also, append to LD_LIBRARY_PATH because ICC uses that for some internal
libraries such as libintlc.so.
